As 2011 rapidly winds to a close, it’s easy to fall back on lists as a way to fill columns – indeed, as a TV critic, it’s my God-given right – but HBO’s announcement this week that it was cleaning house and cancelling “Hung,” “Bored to Death,” and “How to Make It in America” served to convince me that I needed to discuss a number of now-defunct series that lost their bid for continued existence during the course of this year. I’m not talking about shows like “Friday Night Lights,” which had an end-game in sight and wrapped on their own terms. I’m talking about series that effectively had the rug ripped out from under their feet. Believe me, there were a bunch…and I’m still kind of pissed about quite a few of them.

11. Medium (CBS)

After seven seasons on the air and surviving a switch between networks (from NBC to CBS), it’s hard to say that “Medium” didn’t live a good, long life. With that said, however, the show had continued to find new ways to keep things interesting, and with the trio of DuBois daughters growing up and getting their own storylines almost as often as their mom. As such, Allison, Joe, and the gang could’ve easily kept going for another few seasons without any complaints from me.

10. Outsourced (NBC)

Am I going to try to defend my enjoyment of this show? No, I am not, because there’s no point in wasting your time or mine. You may not have thought it was very funny, and if you didn’t, that would be your right. I, however, did. And I still miss it.

9. Law & Order: Los Angeles (NBC)

There’s nothing I dislike more than a series that doesn’t know when to leave good enough alone, and for my part, I don’t know why they felt the need to change the formula and kick Skeet Ulrich‘s character to the curb. Sorry, did I say “curb”? I meant “grave,” of course. Not that there’s anything wrong with giving an actor of Alfred Molina’s caliber a more substantial role, but to do so in midseason can’t have pleased the existing viewership very much. Truth be told, I’d rather they’d just kept the original “Law & Order” around, but in its absence, this was a nice substitute, and it sucks that it never had a chance to really spread its wings.

8. The Event (NBC) / V (ABC)

When it comes to casualties in the alien-invasion field, I can accept the cancellation of “V” a bit more than that of “The Event,” if only because it was a minor surprise that it made it to a second season in the first place. And if I’m to be honest, I’m not really surprised that NBC couldn’t be bothered to give “The Event” a shot at a sophomore year, since they probably figured it’d only let them down the way “Heroes” did. But whereas “Heroes” really dropped the ball in its second year, I felt like “The Event” had a better chance of upping the ante. Guess I’ll never know for sure.
